USB issues are caused by the 15-port limit in macOS, missing USB mapping, or incorrect port configuration.
Step 1 — Understand the 15-Port Limit
macOS limits each USB controller to 15 ports. A USB 3.0 port counts as two (one USB 2.0 + one USB 3.0).
Step 2 — Map Your USB Ports
Use USBToolBox or USBMap to identify which physical ports correspond to which internal port numbers.
Step 3 — Create a USB Map Kext
Generate a USBMap.kext with only the ports you need. Remove USBInjectAll.kext once your map is in place.
Step 4 — Verify in System Information
Open System Information > USB and confirm all expected devices appear.
Expected Results
- All needed USB ports recognise devices
- USB 3.0 ports achieve expected transfer speeds
- No kernel panics when plugging/unplugging devices
